Project description:Custom exome aCGH analysis of copy number across the genomes of 16 canine breeds Two-condition experiment, All breed samples were compared to a single Boxer reference, Seizure samples were compared to breed and sex matched controls, and German Shepherds were compared to the Boxer reference
Project description:Custom exon aCGH analysis of copy number across the genomes of 16 horse breeds Two-condition experiment, All breed samples were compared to a single Thoroughbred reference, Reference was then compared to Twilight (DNA from horse used for reference genome assembly)
Project description:A CNV map in pigs could facilitate the identification of chromosomal regions that segregate for important economic and disease phenotypes. The goal of this study was to identify CNV regions (CNVRs) in pigs based on a custom array comparative genome hybridization (aCGH). We carried out a custom-made array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the pig genome analysing animals of diverse pig breeds (White Duroc, Yangxin, Erhualian, Tongcheng, Large White, Pietrain, Landrace and Chinese new pig line DIV ) using a tiling oligonucleotide array with ~720,000 probes designed on the pig genome (Sus scrofa genome version 9.0).
Project description:CNV plays an important role in the chicken genomic studies,it is imperative need to investigate the extent and pattern of CNVs using array comparative genomic hybridization (aCGH) in chinese chicken breeds for future studies associating phenotype to genome architecture. we describe systematic and genome-wide analysis of CNVs loci in five Chinese indigenous chicken breeds were evaluated by aCGH.
Project description:This study uses a custom made Nimblegen aCGH chip that targeted all segmental duplications in the canine genome to identify associated CNVs. A total of 23 hybridizations were performed in a panel of diverse dogs and a single wolf.

Project description:We carried out a cross species cattle-sheep array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the sheep genome analysing animals of Italian dairy breeds (Sarda, Bagnolese, Laticauda, Massese and Valle del Belice) using a tiling oligonucleotide array with ~385,000 probes designed on the bovine genome. We identified 135 CNV regions (CNVRs) covering about 10.5 Mb of the virtual sheep genome referred to the bovine genome (0.398%) with a mean and median equal to 77.6 kb and 55.9 kb, respectively. A comparative analysis between the identified sheep CNVRs and those reported in the cattle and goat genomes indicated that overlaps between sheep and goat and sheep and cattle CNVRs are highly significant (P<0.0001) suggesting that several chromosome regions might contain recurrent interspecies CNVRs. Many sheep CNVs affect genes with important biological functions. Further studies are needed to evaluate the functional relevance of these CNVs. In this study we made use of the high conservation and homology between the cattle and sheep genomes determined by their phylogenetic closeness to identify CNVs in sheep applying the same approach we carried out to identify CNVs in the goat genome. We used a custom tiling array including ~385,000 oligonucleotide probes designed on the Btau_4.0 version of the Bos taurus genome assembly and analysed genomic DNA samples of 11 sheep belonging to 6 different Italian dairy sheep breeds (2 Sarda, 2 Bagnolese, 2 Comisana, 2 Massese, 2 Laticauda and 1 Valle del Belice) compared to the reference DNA of another Sarda sheep.
Project description:This study centered on using a custom made Nimblegen aCGH chip that targeted all segmental duplications in the canine genome to identify associated CNVs. A total of 19 hybridizations were performed in a panel of diverse dogs and a single wolf. Using computational approaches all segmental duplications were identified in the canFam2 genome of the dog. A custom aCGH chip was then built that densely interrogated these segmental duplications for CNVs in a panel of diverse dog breeds and a single wolf.
Project description:Discovery of common Asian copy number variants using a novel integrated high-resolution array CGH and massively parallel DNA sequencing. We attempted to discover common Asian copy number variants (CNVs) from the DNA of 30 Asian women (10 Korean, 10 CHB (HapMap), 10 JPT (HapMap)) using a custom-designed 24M-oligonucleotide Agilent platform (1.1M X 24 slides). The reference sample for aCGH was NA10851 (HapMap CEPH). In addition to the 30 women, 3 more individuals were analyzed as controls (AK1 (Kim, J.I. et al., 2009 Nature), NA12878 and NA19240).
